trans question

[Michael_e]

Will a 700r4 that was connected to a 4.3 bolt up to a 283 small block? will this trans handle the power of a stock 283?

Hi Mike;

I have a 700r4 hooked up to a 4.3 in my 95 chevy pu.
It had a 5sp in before.
I know that the bolt pattern on the block n trans are the same.
The 700r4 should do good behind the 283,unless you have beefed up the 283.
You will have to make or bye a NEW drive line as the 700r4 about 4" longer then reg trans.

You might consider doing thorough inspection of the trans and installing a thicker shift plate and hd clutches, just to be sure - and check the speedometer drive, some are mechanical and the others are electric.

I put a 700r4 behind a '99 350, the '51 should be a few 100 lbs lighter that the trucks they came out of.

Why would I want or need a thicker shift plate? I'm not necessarly looking for hard or tire burning shifts, just good, reliable service.

Just for long term reliability. I have heard of complaints on the 700r4 getting weak at 60,000 +/- miles, and I plan on driving mine farther too. I'd just rather fix it the first time.....just sharing the idea.

Thanks for the info, Don!
Is the thicker shift plate an option on trans rebuild kits that you specifically have to ask for when ordering? Or, is it only available thru certain parts suppliers?

Plate was ordered, as were the RedLine clutches, I don't know if they are packaged specifically as a kit -

maybe some of the more experienced builders here will add to the topic.

I've had problems with EVERY 700R4 that I've owned. They have a design flaw with the valve body system that will turn the insides of your trans to silly putty it the T.V. cable is even a milimeter out of adjustment. However, theye are beefy, have a very low first gear, and a decent overdrive. They were the stock transmissions behind every IROC camaro and most C-4 Corvettes, so yes, they will work with a 283, and will definetly handle the torque just fine.

Here is a link to a valve body upgrade that will make your trans last, especially if you use a cobbled together T.V. cable & bracket that you wouldn't normally be able to properly adjust. I wish this would have been around in the early 2000's because it would have saved me 3 rebuilds and I'd probably still have my '89 IROC!

I'm not a 700-R4 expert but I did sleep at a Holiday Inn Express last night.

Here's a link to my 700-R4 build: http://67-72chevytrucks.com/vboard/s...d.php?t=490570

It would also be nice if Clinebarger reported in on this one to save you a lot of grief...

The short answers to your questions are "Yes" and "Yes".

I don't see a fairly stock 283 having enough more power than a 4.3 and it may not have as much hp or torque than some 4.3 engines, to get worried 700-R4 about.

The thing on a 700-R4 is and always has been the TV cable adjustment. It has to be perfect or else you have problems as Oneoffstroker mentioned in post #9. They just are not a forgiving trans if you get that adjustment off even the least bit.
